  [摘要] 目的 探?产KPC酶肺炎克雷伯菌的临床感染分布特点及中西医结合的干预效果。 方法 收集临床多个科室标本,共筛查出产KPC酶肺炎克雷伯菌株523株,分析其临床分布情况及病区分布情况。将配置好的头孢三嗪、鱼腥草注射液、穿琥宁注射液分别单独或与西药配伍加入适当浓度的产KPC酶肺炎克雷伯菌落中,经动态比浊法测定内毒素含量。 结果 在临床分离出的523例产KPC酶肺炎克雷伯菌株中,来自于呼吸道标本所占的比率最高,其次为中段尿液、脓液及伤口分泌物、血液。在各标本中产ESBLs阳性率最高的为呼吸道标本,其次为脓液及伤口分泌物、血液、中段尿液。产KPC酶肺炎克雷伯菌的临床病区分布情况:呼吸科所占比率最高,其次为ICU、感染科、泌尿外科。产ESBLs情况也存在明显差异,ICU所占百分比最高,其次为肿瘤科、呼吸科、感染科。鱼腥草组、穿琥宁组及与西药配伍组内毒素产生的量均明显低于西药组(P http://

  [Abstract] Objective To investigate the characteristics of infection distribution of KPC-producing Klebsiella pneumoniae and its intervention effect of integrated traditional Chinese and western medicine. Methods A total of 523 strains of KPC-producing Klebsiella pneumoniae were screened from various clinical departments, and its clinical distribution and distribution of disease areas were analyzed. Ceftriaxone, Houttuynia injection, and Chuanhuning injection which were well-prepared were added into appropriate concentration of KPC-produing Klebsiella pneumoniae colony alone or combined with western medicine. The endotoxin content was determined by dynamic turbidimetry. Results In the clinically isolated 523 cases of KPC-producing Klebsiella pneumoniae strains, the highest proportion was from respiratory specimens, followed by the middle segment of urine, pus, wound secretions, blood. The highest ESBLs-producing positive rate in each specimen was from respiratory specimens, followed by pus, wound secretions, blood, middle segment of urine. The distribution of clinical ward of KDS-producing Klebsiella pneumoniae: Respiratory rate accounted for the highest rate, followed by ICU, department of infectious diseases, and urology. ESBLs production was significantly different. ICU accounted for the highest percentage, followed by the Department of Oncology, Respiratory Medicine, and Infectious Diseases. The amount of endotoxin produced in Houttuynia group, Chuanhuning group and integrated western medicine group was all significantly lower than that in western medicine group(P    在我国,关于中医药在抗内毒素方面的研究日益广泛,研究[9-11]证实,清热解毒作用的中药在抗内毒素方面效果明显。本研究选择了鱼腥草、穿琥宁两种清热解毒药物,分别采用单独和西药配伍方案应用于产KPC酶肺炎克雷伯菌的抗感染研究中。鱼腥草来源于三白草科植物,能清热解毒、消肿疗疮、利尿除湿、清热止痢,现代药理学证实鱼腥草具有抗菌、抗病毒等作用[12-14]。穿琥宁属于免疫系统用药,对细菌内毒素引起的发热有较强的解热作用[15-17]。本研究发现,单纯中药组及中西医配伍组的产KPC酶肺炎克雷伯菌释放内毒素的量均明显低于西药组,这与其他学者的研究基本一致,也证实了中药在抗内毒素方面的显著效果。
  综上所述,本研究对于产KPC肺炎克雷伯菌的临床分布特点有了初步的认识,今后对于相应的灭菌工作可以更加有针对性地开展。在今后的研究中,将制定并执行相关灭菌守则和操作,以期减少产KPC酶肺炎克雷伯菌的临床感染发生率。中药与西药配伍后对于产KPC酶肺炎克雷伯菌的产内毒素效应有明显的抑制作用,理论上能够降低内毒素释放入血的浓度[18-20],今后将开展相关研究,探讨中药对于KPC肺炎克雷伯菌感染相关疾病方面的临床疗效及预后。
